K-R's DD omits this chap and makes his 'son' Jordan to be the wife of Mabel of Gloucester. So far Ronny Bodine's account in 1999 get more marks!

This installment presents the earliest generations of the family that are
presently known. The format follows the previous three installments of the
Champernouns of Modbury, Ilfracombe and North Tawton. Any disagreement with the content is welcome. As before, the most prevalent forms of individual names have been used here.

GENERATION 1

1. JORDAN de CHAMBERNUN. Seigneur de Cambernon and Maisoncelles in Normandy, France. In 1146 Jordan de Campo Ernulfi was first witness of a confirming charter of Henry de Tracy, then Baron of Barnstaple to the Priory of St. Mary Magdalene, Barnstaple, Devonshire. He appears to have died by 1166, when his sons Jordan and Henry were in possession of his lands.

He married, as her first husband, Mabel, daughter of Robert, son of
Robert, Earl of Gloucester, and Hawise, daughter of Baldwin de Redvers, 1st
Earl of Devon. Mabel married 2ndly, William de Soliers. As Mabel de Soliers, she confirmed in c1193-1204 a gift charter of the manors of Fleet and Ibberton, Dorsetshire from her mother, Hawise, to her son, Richard de Chambernun.
(Charters of the Redvers Family, 11, 146; DCNQ, 18: 3-7, 81-84, 108-112,
319-320)
Children:

2. Jordan de Chambernun, m. Emma de Soligny.

3. Richard de Chambernun.

4. Henry de Chambernun, m. Rose de Tracy.

That Robert, a little known son of the Earl of Gloucester was even married, is
revealed in a charter dated between June 1141 and 1161, probably before Oct
1147, in which Hawise, daughter of Earl Baldwin de Redvers, made a gift to
Quarr Abbey jointly with her husband, Robert, son of the Earl of Gloucester.
CP, 5: 686 states Robert was a natural son of Earl Robert and that he was named c1160 in a charter and is addressed in a writ from King Henry II as Castellan of Gloucester.

GENERATION 2

2. JORDAN de CHAMBERNUN. He predeceased his mother and was buried at Christchurch Priory before 1214. In the Scutage Return of 1166 he was holding the old Cambernon fief in Normandy and 7 knights' fees in the Honour of Gloucester in England, including 2 knights' fees in Umberleia (Umberleigh) and Becintone (High Bickington). In 1189 he confirmed his brother Richard's gifts (Cal. Doc. France, I. no. 563). In 1190 he was lord of 16 knights' fees "in Devon and Cornwall" (Red Book of the Exchequer, p. 607).

He was married to Emma de Soligny, named in a IPM of 1302 (CIPM, 4, no.

82) wherein she is called Emma de Sulenny, sister and heiress of Geoffrey de
Sulenny (who died 1265/6) and mother of Oliver de Campo Arnulphi. (Although the IPM calls her son Oliver, there is little doubt he is identical with
William.)
Children:

5. William de Chambernoun, m. Eva de Whitchurch.

3. RICHARD de CHAMBERNUN. In 1189 he gave the Church of St. Cornier to the Canons of Yvrande (Cal. Doc. France, I, no. 562). In 1193-1214, he confirmed the gift of his grandmother, Hawise de Redvers, to his brother of the manors of Fleet and Ibberton, Dorsetshire (Charters of the Redvers Family, p. 146).

4. HENRY de CHAMBERNUN. Henry is named as brother of Jordan de Chambernun in the Cartulary of Montebourg. In 1166 he was in possession of the family estates under the Honours of Barnstaple and Okehampton. He was lord of 1 fee under the Honour of Gloucester in 1201-1212 (Red Book of the Exchequer, p. 154) and in 1211-1212 (Red Book, p. 607). Henry appears to have died in 1211 or 1212, for Rose de Campo Ernulfi is also shown as holding 1 fee--probably the same--under Gloucester in 1210-1212 (Red Book, p. 559).
He was married to Rose (or Rohese), living 1237, apparently daughter and
heiress of Sir William de Tracy. Rose married 2ndly Robert de Sechevill (or
Sacchville), died c1218, of Braunton, Cowley, Dunsford & Rewe, Devonshire. Rose was heiress to Clistwick, Devonshire (later Clist St. George or Clist Champernowne), this manor being previously the maritagium of Sir William de Tracy's wife. In 1237 Rose was holding as dower from her late husband the manor of Rewe (Book of Fees, p. 612).
